According to your link, yes. Hot weather leads to diminished “coital frequency," according to a new working paper put out by the National Bureau of Economic Research. Three economists studied 80 years of U.S. fertility and temperature data and found that when it’s hotter than 80 degrees F, a large decline in births follows within 10 months.
Would-be parents tend not to make up for lost time in subsequent, cooler months. (A rebound in subsequent months makes up just 32 percent of the gap).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
